Lord knows if this Giants start is a quirk or a harbinger, it will change once Arizona disappears from their schedule, when Angel Pagan and Brandon Belt are reminded that the game is not supposed to look this easy, every break seems to go their way and they get beach weather for the home opener.

Hard questions are for losing. Winning teams just ride the wave as long their performances and good fortune allow.

The Giants opened their AT&T Park schedule Tuesday with a 7-3 victory, their sixth win in the first eight games and fourth in five against the Diamondbacks, which let 42,166 fans see in person what they saw on television last week.

Belt homered again, his fifth. Pagan singled, doubled and walked in his sixth multihit game, Michael Morse hit a two-run single and a double, Brandon Crawford had a two-run hit and Tim Hudson improved to 2-0 in the new uni.

Hudson allowed his first three runs as a Giants, two earned, but finished eight innings and got a nice ovation after Paul Goldschmidt’s on his 101st and final pitch.

After Belt hit four home runs on the seven-game trip to start the season, the question was whether he could hit them at home. Of his 17 last year, only six came at AT&T Park.

Belt needed one at-bat to provide a partial answer. On a warm day with little wind he had no trouble turning on Trevor Cahill’s low, inside fastball and slamming it into the fat part of the Arcade in right-center, giving the Giants a 2-0 lead.

By game’s end the Giants had xx runs on the season, impressive for any eight-game stretch, more so while the No. 3 and 5 hitters are struggling. Pablo Sandoval and Hunter Pence both are mired in the .100s.

Manager Bruce Bochy presented Brandon Hicks with a nice honor, picking the journeyman among his three second basemen for his first major-league start in an opener.

“The fact he’s starting the opener is a credit to how he played this spring and how he’s played so far,” Bochy said. “That’s why I gave him the nod. I’m excited for him.”

Hicks surely would like the second inning back. With the Giants leading 2-0 on Belt’s homer, and two runners on, Mark Trumbo hit a double-play ball to Pablo Sandoval. Hicks had to lean to catch a wide throw for the force then made his own bad throw on the relay, past Belt and into the stands.

Hicks could have taken more time with Trumbo running.

Martin Prado was awarded home plate for the first run that Hudson allowed as a Giant. It was not earned.

The Giants wasted little time widening their 2-1 lead, scoring the way they should in a rally that begins ti the leadoff and No. 2 hitters, Pagan and Belt, going double-single to start the inning.

The middle of the order converted that into three runs, one on a Buster Posey single, two more on a well-placed Morse single through the right side. Pence bought the Giants a run by stealing second before the hit.

The Giants led 5-2 when Crawford got a two-out, two-strike, two-run single against a lefty, Ryan Rowland-Smith, for a 7-2 lead in the sixth. The inning should have been over with Morse’s fly to the warning track in left, but Trumbo had trouble following it from the time it left Morse’s bat.

It hit the track beyond his glove and bounced into the seats for a ground-rule double.
